|Graver Gal||RE: Charles Woodrow Gregory|
I got the information for Charles from the Missouri Digital Heritage site. You can go there, and when you get to the death certificate search, you can search names, counties, death dates. They also have a advanced search.
But the dates are from 1910-1965, so you may not find William, but you may find Belle if she lived past 1910.
Just so you know, the Belle Harris Gregory who died in 1936 is probably not your Belle. She is buried at Bellefontaine Cemetery at St. Louis and her husband is listed as Charles and a son is listed as Charles Sherman Gregory, 1895-1898. The other Belle Gregory is married at her death, and to a Will Gregory but he died in 1959. So again, probably not your Belle.
If I find more, I will let you know.
